Cascode Current Source
... Another advantage of this technique is that the current mirror ratio depends not just on transistor matching but also on the matching of the two RE resistors. The overall matching obtained is usually better than you would get from two transistors alone. This current mirror only works well for that n ...

This prevents the instruments from being “pegged” (forcing the needle off scale) and possibly damaged, should the magnitude of the voltage or current exceed the smaller scale limits.

... This time the possible cross-products are K with SO4 and Ag with PO4. Let’s check whether either of these meets one of the three criteria: K-SO4 is not insoluble (by rule #1); it is not a weak acid (no H); and it is not a decomposer. So we know K and SO4 are out of the running. We can see by rule #4 ...

Nanofluidic circuitry
Nanofluidic circuitry is a nanotechnology aiming for control of fluids in nanometer scale. Due to the effect of an electrical double layer within the fluid channel, the behavior of nanofluid is observed to be significantly different compared with its microfluidic counterparts. Its typical characteristic dimensions fall within the range of 1–100 nm. At least one dimension of the structure is in nanoscopic scale. Phenomena of fluids in nano-scale structure are discovered to be of different properties in electrochemistry and fluid dynamics.
